SELF-FILLING FOUNTAIN-PEN.

Application filed Becember 28, 1909.

To all whom it may concern:

Be it known that I, Gnonen H. HnixnsnL- MAN, a citizen of the UnitedStates, residing at Provo, in the county of Utah and State of Utah, haveinvented certain new and useful improvements in Self-FillingFountain-Pens, of which the following is a specification.

This invention relates to fountain pens, and has particular reference tothat type of fountain pens which are designed to contain withinthemselves the means for filling the same.

The invention consists of certain specific details of constructionhereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a longitudinal section ofthe device, showing the parts in normal position; F ig. 2 is a viewsimilar to Fig. 1, but with the parts in the opposite position; Fig. 3is a face view of the upper end of the device indicating the positionassumed by certain of the parts preparatory to filling; Fig. fl: is atransverse section on the line all of Fig. 1, and Fig. 5 is a detailsectional view on the line 5-5 of Fig. 2, the end cap being removed.

Throughout the following description and on the several figures of thedrawing similar parts are referred to by like reference characters.

The invention illustrated includes a pen barrel 10, adapted to haveconnection to its lower end in any suitable manner and any desired typeof pen and feeding devices, the same constituting a partof this presentinvention. lVithin the barrel is a flexible bag 11 adapted to carry theink and supply it through the feeding devices to the pen in a mannerwell understood in this type of fountain pens. The bag 11 in its normalposition substantially fills the interior of the barrel 10.

As is customary in this type of fountain pens there are means providedfor the pur pose of compressing or collapsing the bag preparatory to thefilling or refilling operation. In this instance such means include aplate 12 which is substantially fiat and coextensive with the bagthroughout the greater portion of the length of the latter. The plate iscomparatively thin but must be made of some suitable stiff material sothat when pressure is applied thereto toward the bag it will collapsethe same, driving the in- Specification of Letters Patent.

closed air therefrom. The peculiar means for operating the platecomprise a U-shaped bail or stirrup 13, the ends of which extend inopposite directions and constitute a pair of trunnions 13 in the sameaxis. The trunnions are ournaled in a pair of bearings 11 in oppositesides of the barrel 10. The portion of the bail 13 between the trunnionsis substantially semicircular so as to substantially conform to the formof the barrel and the form of the bag when in normal position, the bagwhen in normal position extending within the bail between the trunnionsthereof. The bail is permanently con-- nected to the aforesaid plate 12as by a pair of cars 12 to which the bail is pivotally connected, theears lying on opposite sides of the link 17. A pull rod 15 movablymounted within the barrel and is adapted to slide longitudinallythereof, being adapted to be operated by a finger-piece or knob 16 whichextends to the outside of the barrel. The inner or lower end of the pullrod is connected by means of a link 17 to the middle portion of the bail13, the ends of the link 17 being pivotally connected to the pull rod 15and bail 13, respectively.

The parts just described are so arranged and proportioned that a pullupwardly or outwardly on the finger-piece 16 will cause the bail 13 tobe turned around the axis of the trunnions 13, whereby the plate 12 willbe forced against the bag and toward that side of the barrel oppositethe pull rod 15. The link 17 may be of any suitable or de sired length,but preferably it is designed to be substantially of such length thatwhen the pull rod is drawn upwardly or outwardly to compress the bag thelink will occupy substantially a perpendicular position with respect tothe barrel, whereby the compressing devices will be locked in suchposition as shown in Fig. 2.

The outer end of the barrel 10 is normally closed by means of a cap orplug 18 connected in any suitable manner thereto. As indicated said plugis provided with screw threads 18 whereby the cap may be securelyfastened in place. The cap 18 serves not only to close the barrel,presenting a finished appearance, but also serves as a locking means tocontrol the operation of the pull rod 15. The cap is shown as beingprovided on one side with a groove 18, which when the cap is loosenedmay be made to register or come into alinement with the outer end of thepull rod 15 and through or along which the said pull rod may be drawnfor the purpose above indicated. The pull rod near its outer end is bentsharply as indicated at 15' so as to place the finger-piece 16 in aplane outside of the plane of the main portion of the pull rod andwhereby the finger-piece may be grasped with the finger or thumb nail.The extreme outer end of the pull rod lies normally within a notch 10 ofthe barrel. Then the cap is turned to its normal tight position thegroove 18 will be out of alinement with the pull rod and the cap willtherefore prevent the pull rod from being drawn outwardly. In order toprevent the pull rod from being drawn outwardly too far it is preferablyprovided with one or more pro jections or processes 15 which will strikeagainst the ends of the shoulders of the cap forming the groove 18.

With the parts in the position indicated in Fig. 1, assuming that thebag is empty and is to be filled with ink, the cap 18 will be turned soas to bring the groove 18 into position to receive the pull rod 15, atwhich time the pull rod may be drawn outwardly so as to causecompression of the bag to drive the air therefrom. The operation thusfar may be performed at any time, either before or after inserting thepen end of the device into the ink, and the parts will be heldsubstantially in the position indicated in Fig. 2 by virtue of thelocking effect of the link 17. After the pen is dipped into the ink aslight downward pressure upon the finger-piece 16 will serve to unseatthe link 17 from its locking position and thereafter the resilience ofthe bag 11 will cause the same to assume its normal position causing theink to fill the same in the well-known manner. After the parts have beenrestored to the normal position indicated in Fig. 1 the cap 18 will beturned to lock the same in such position. The device ismade of a smallnumber of parts, and hence is not likely to get out of order.

The several operating devices may be made of any suitable materials, andthe relative proportions of the parts may be varied to a considerableextent if desired without departing from the spirit of the inventionhereinafter claimed.

I claim:

1. In a self filling fountain pen, the combination with a barrel and theresilient ink bag therein of a ball journaled within the barrel on atransverse axis and extending upon opposite sides of the bag, a plateassociated with the bag and operable by said bail, a pull rod connectedto the bail to swing the same on its axis to cause the plate to compassthe bag, and a cap connected to the upper end of thebarrel to engage andthereby control the operations of said pull rod, said cap beingrotatably connected to the barrel, substantially as set forth.

2. In combination, a pen barrel, a col lapsible ink bag therein, meansto cause the bag to collapse, said means including a pull rod, and meansto control the movements of the pull rod, said last mentioned meanscomprising a cap having rotary connection to the outer end of the barreland being provided with a longitudinal groove adapted to register withthe outer end of the pull rod in one position and in another position tohold said pull rod in its normal inoperative position.

In testimony whereof I affix my signature in presence of two witnesses.
